摘要:
Methods and apparatuses for re-instantiating a firmware environment that includes one or more firmware functions available at pre-boot time when transitioning the computing device from a wake state to a sleep state. A network event received by the computing device while in a sleep state may be handled by the firmware environment independent of the operating system and without returning the entire computing device to the wake state.

A method and system for recovery of a computing environment includes monitoring during a pre-boot phase and a runtime phase of a computing device for selection of a hot key sequence by a user and performing a recovery action in response to the selection of the hot key sequence by the user. The recovery action may be any one of a number of predetermined and/or selectable actions such as restoring system defaults, migrating memory, displaying a menu of options, setting various software flags, restarting or rebooting the computing device, and/or the like.

Methods and apparatus to provide dynamic messaging services are disclosed. An example method includes determining, in a pre-boot environment, supported dimensions for display of information on the display screen; generating, in the pre-boot environment, restricted dimensions that are less than the supported dimensions; providing the restricted dimensions to an operating system of a virtual machine supported by a virtual machine manager, wherein the restricted dimensions define a boundary between a first screen portion and a second screen portion; displaying first information in the first screen portion and displaying second information in the second screen portion; and preventing, via the virtual machine manager, elimination of the first screen portion from the display screen.

In some embodiments, the invention involves a platform-based firmware to provide a programmable scheduling timer interval. Dynamic scheduling intervals for non-interrupt driven device drivers and services utilize polling to determine device activity. In at least one embodiment, the disclosed subject matter reduces power consumption of a platform by decreasing the frequency of the system timer-tick when the platform is running in a lower power state. Other embodiments are described and claimed.

A method for accessing a protected area of a solid-state storage device via firmware control is described. During system initialization, firmware components are loaded and executed to initialize a computer system. These firmware components include a firmware driver for accessing solid-state storage devices connected to the computer system. The system firmware enables a protected area on a solid-state storage device's media to be accessed under firmware control. After firmware accesses, the protected area is closed from access by non-firmware entities by “hiding” the true size of the media such that those entities are unaware of this area of the media. Mechanisms are disclosed for providing firmware access to the protected area only during pre-boot, and for both pre-boot and run-time operations. The firmware-controlled media access scheme may be used to load firmware stored on solid-state media during pre-boot and to store system information in the protected area during pre-boot and/or run-time operations.

A method and apparatus for seamless frequency sequestering is herein described. In response to a frequency throttle event, controlling software, such as an OS, is provided access to a throttled amount of frequency associated with the frequency throttle event, while another amount of frequency is transparently sequestered for performance of non-controlling software tasks.

The present disclosure relates to a technique or device to allow hardware related drivers to present a centralized configuration program and, more particularly, to a technique or device to allow hardware related drivers to present configuration information to a centralized user interface manager.
摘要:
In a computing system, sharing a physical NIC device among multiple virtual machines may be implemented by a customer virtual machine by receiving, by a virtual network interface card (NIC) driver of a customer operating system (OS) running in the customer virtual machine on a computing system, a customer OS request packet for transmission by a physical NIC driver over a network coupled to the computing system, and copying at least a portion of the customer OS request packet into a free block of shared memory of the computing system and appending the block to a transmission queue in the shared memory. Next, a service virtual machine may support the implementation by fetching the block from the transmission queue by a virtual NIC driver of a service OS running in a service virtual machine and packaging the portion into a service OS request packet, passing the service OS request packet to a service OS network stack component of the service OS, routing the service OS request packet, by a bridge driver of the service OS network stack component, to the physical NIC driver, and sending the service OS request packet over the network by the physical NIC driver.
摘要:
A computer system is partitioned during a pre-boot phase of the computer system between a first partition and a second partition, wherein the first partition to include a first processing unit and the second partition to include a second processing unit. An Input/Output (I/O) operating system is booted on the first partition. A general purpose operating system is booted on the second partition. Network transactions are issued by the general purpose operating system to be performed by the I/O operating system. The network transactions are performed by the I/O operating system.
